After the discovery during a playground inspection, the affected area was cordoned off and the object was initially examined by the police with a sniffer dog. As it could not be clearly identified, the explosive ordnance disposal service of the state of Rhineland-Palatinate was called in. During its examination on March 6, 2026, it was determined that the object was the base of a bomb from World War II. The find was disposed of properly. The explosive ordnance disposal service informed the city of Mainz today that there was no danger at any time, as the bomb base was a harmless piece of metal. Further investigation of the outdoor area is not necessary. The outdoor area of the Rasselbande daycare center can therefore be used again without restriction and without danger. The daycare center will resume normal operations on Tuesday, March 10, 2026.
